acpi: drop build_piix4_pm()
The _SB.PCI0.PX13.P13C opregion (holds isa device enable bits) is not used any more, remove it from DSDT. piix4 DSDT changes: Scope (_SB.PCI0) { - Device (PX13) - { - Name (_ADR, 0x00010003) // _ADR: Address - OperationRegion (P13C, PCI_Config, Zero, 0xFF) - } - } - - Scope (_SB.PCI0) - { Device (ISA) { Name (_ADR, 0x00010000) // _ADR: Address OperationRegion (P40C, PCI_Config, 0x60, 0x04) } } Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Igor Mammedow <imammedo@redhat.com> Message-Id: <20200619091905.21676-11-kraxel@redhat.com> Reviewed-by: Michael S.
